Ihe complete burner and its standard l6 may of course be removed'as an assembly by merely lifting out, after disconnecting the fuel line.

The fuel drips down from the needle valve and fuel pipe onto the bottom of the shallow recess 20:, then flows into and over the several concentric grooves 2|, 22, 23 and finally reaches the outer channel 24. Combustion takes place in the flat open space between the burner top and base. flows into the interior of the stove through the opening I3 and between the fingers 33, there .being ample space thus provided for efiicient combustion as the burner is wholly below the opening except for the tips of the fingers, as shown in Fig. 1. A pivoted damper or air valve 36 may be swung horizontally over the top of the stove partially to close the air inlet during mild weather or completely close it when the burner has .been removed, and a latch 31 fixed to the stove top will fit over the damper to lock it when it is swung to closed position. The outer vertical edges of the fingers barely clear the edges of the air opening l3 so that if the burner is tipped even slightly one of the fingers will engage the edge of the air opening to prevent further tipping. Thus the comparatively small base offered by the standard 16 is a satisfactory support for the burner.

In lieu of the tubular standard [6, a solid rod 40 (Fig. 6) may be employed, said rod having a reduced lower end 4| which extends through an aperture 42 in the bottom Hi of the stove body, with the shoulder formed by the reduced lower end 4i resting on the bottom as shown. The upper end of rod 40 may be secured to boss l8. This construction is advantageous if it is desired to have no obstruction on the interior of the stove body such as would interfere with cleaning.

It will be particularly noted that the location of the standard (16 or 40) in the center of the burner and extending straight down, plus its small lateral dimension, insure no interference with or deflection of the flames of combustion, which are free to extend outwardly from the periphery of the burner in all directions. Only the two pairs of ears 26, 21 slightly obstruct the flames and these are of the proper design to withstand the heat and present very little hindrance to the fiow of air and free combustion.

.Either standard H5 or 40 is prevented from shifting laterally on the stove bottom by the means which supports it at its lower end; however both standards are readily lifted off the stove bottom and as readily replaced.

While embodiments of the invention have been described in considerable detail, the invention is not limited to the details of the disclosure but may assume a variety of other forms.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In combination with a stove body having a bottom and a top, the top being provided with an air inlet; a burner having a base and a top secured to and slightly spaced from the base; means supporting the burner within the stove body just below the air inlet; said means comprising a relatively thin elongated standard secured at its upper end to the underside of the burner base at its center and adapted to be supported at its lower end directly upon the stove bottom; means on said stove bottom co -operating Air 4 with said standard to hold the standard in an upright position with lateral shifting upon the stove bottom made impossible, said means however permitting detachment of the standard therefrom by mere lifting of the standard; and liquid-fuel-delivering means disposed above the .burner and discharging the fuel by gravity centrally of the burner into the space between the top and the base so that the fuel may fiow from the center of the base in all directions toward the perimeter of the base.

2. In combination with a heating stove having a bottom; upstanding means fixed to the stove bottom a tubular vertical standard fitting over but removable from the upstanding means and having screwthreads on its upper end; a burner base screwed at its center to the upper end of the standard; a burner top secured to the burner base in spaced relation thereto; and liquid-fueldelivering means connected to the burner top and adapted to discharge fuel by gravity into the space between the burner top and base; the standard constituting the sole support for the burner and in turn receiving its sole support from the stove bottom.

3. In combination with a heating stove having a body with a bottom and a top, the top being provided with an opening providing an air inlet; a burner for liquid fuels adapted to be introduced into the stove body through said air inlet; burnersupporting means consisting of a straight standard secured at its upper end tothe underside of the burner, the lower end of the standard having a reduced extension fitting an aperture pro-- vided in the bottom of the stove; the burner being supported by the standard just below the air inlet so that air may freely enter the interior of the stove body; a plurality of upstanding finers on the burner which, when the burner is in position, extend upwardly through the air inlet and may contact the edges of the air inlet in the event of tilting of the burner on its support; and liquid fuel delivery means discharging by gravity into the burner at the center thereof.

4. In combination with a burner having an open area between its top and bottom in which liquid fuel may flow; means discharging liquid fuel to said open area; :a relatively thin upright burner-supporting member; means to detachably secure the upper end of the upright supporting member to the middle of the underside of the burner, the lower end of the upright supporting member being adapted to be supported on the bottom of a stove; and upstanding fingers fixed to the burner top at the perimeter thereof and adapted to engage or be slightly spaced from the horizontal edges of an opening in the top of the stove.
